Designing and implementing the cognitive worlds of people

Genta G.’s icon

Genta G.

I'm drawn to where technology meets culture: speculative fiction and human-computer interaction, people themselves and the things they make, and where all of it is heading.
I design from people's mental models, and I build what I design.
